The Mets have activated Jason Bay from the disabled list, the team announced.

To make room on the active roster for Bay, the Mets designated Omar Quintanilla for assignment.

In 29 games for the Mets this season, Quintanilla hit .257 with five doubles, one home run and four RBI in 70 at-bats. He had just one at-bat in two appearances in July.

Michael Baron: Now that Quintanilla is off the 40-man roster, the Mets have flexibility to add Matt Harvey to the 40-man roster, should they choose to promote him. It’s still not clear whether or not Harvey gets promoted – presumably the Mets will make that call closer to Saturday, when either Harvey or Miguel Batista have to start.
